The « special inheritance rules » of the lex situs introduce a particular exception to the unitary system of the law applicable to succession. Its recognition by the recent Regulation (EU) No 650/2012 of the European Parliament and of the Council of 4 July 2012 on jurisdiction, applicable law, recognition and enforcement of decisions and acceptance and enforcement of authentic instruments in matters of succession and on the creation of a European Certificate of Succession demonstrates the importance and the current relevance of this legal provision. We find the immediate precedent of the rule in Article 15 of the Convention of 1 August 1989 on the Law Applicable to Succession to the Estates of Deceased Persons, which also inspired Article 3099 par. 2 of the Civil Code of Quebec. The original conception of the rule comes from Article 28 of the Introductory Act of the German Civil Code of 1896. These legislations acknowledged the necessity of giving effect to some special provisions on succession whose material content legitimates an exceptional breach of the unity in international successions. Therefore, the traditional conflict between the scission and the unitary system of the law applicable to succession finds a conciliatory factor in the observation of the “special provisions” of the lex rei sitae over some particular assets of the estate notwithstanding the conflict rule. The intention is to preserve a minimal content of the State’s law where certain assets are located against the threat that a foreign lex successionis brings about. This uncompromising set of rules presents itself as a bridge to close the gap between these two extreme solutions. It does not contemplate the classic meaning of scission based on the movable or immovable nature of the property (territorial scission), but it breaks nonetheless the principle of unity, in favor of certain substantial considerations derived from the economic, family or social function of some specific assets, by means of a special connection to the lex situs.
